The reduced genetic diversity which results when a population is descended from a small number of colonizing ancestors.
〔生〕建立者效应
Example sentencesExamples
The differences between replicates possibly result from a founder effect.
This large number of reported inherited diseases has two main causes: the close surveillance to which dogs are subjected, and the founder effect and inbreeding practiced in pure-bred dogs that uncovers recessive disease alleles.
This is best explained by a male founder effect during the colonization of northeast India that is estimated to have occurred within the past 4,000 years.
The two-dimensional pattern of colonization also played a major role, increasing the number of source populations for each newly founded population and thus strongly reducing the founder effect.
Demographic history appears to have been stable for the auklets throughout the past several million years, and a founder effect associated with their speciation is unlikely.
